Technical Field

[0001] The utility model relates to the technical field of prefabricated buildings, and more specifically, to a node connection structure between an ALC partition board and a main member. Background Art

[0002] With the development of prefabrication, the entire construction industry is in the process of modernization and industrial transformation and upgrading. Autoclaved sand-lime aerated concrete (ALC) wall panels are building materials with advantages such as light weight, heat insulation, sound insulation, fire prevention, earthquake resistance, energy conservation, and environmental protection. This material is particularly suitable for steel structure prefabricated buildings, which can greatly improve construction efficiency, effectively shorten the construction period, and reduce environmental pollution.

[0003] However, cracks are likely to appear at the joints between autoclaved sand-lime aerated concrete (ALC) wall panels and the columns, walls, and beams of the main structure. Autoclaved sand-lime aerated concrete (ALC) wall panels are generally used for the internal partitions of frame structures or frame-shear wall structures and are installed later. The linear expansion coefficients of concrete components and ALC wall panels are quite different. Due to the deformation difference caused by temperature changes, deformation or cracking occurs at the joints between ALC wall panels and concrete components. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a node connection structure between an ALC partition board and a main member to solve problem X.

[0005] The technical solution of the utility model is as follows: A node connection structure between an ALC partition board and a main member includes a plurality of ALC partition boards and a first structural member. The plurality of ALC partition boards are arranged side by side. A first U-shaped clip is provided at the joint between two adjacent ALC partition boards. The first U-shaped clip surrounds the top corners of two adjacent ALC partition boards. An embedding groove is provided at the center position of the side end of one of two adjacent ALC partition boards, and an embedding block is fixed at the center position of the side end of the other of two adjacent ALC partition boards. When the plurality of ALC partition boards are spliced, the embedding block is clamped in the embedding groove, and there is a plate joint between the embedding block and the embedding groove. The width of the plate joint is less than or equal to 5 mm. The width of the joint between the ALC partition board and the first structural member is 10 mm - 20 mm. The plate joint and the joint are filled with bonding mortar.

[0006] Further, the first structural member is a structural wall or a structural column.

[0007] Further, an alkali-resistant fiberglass mesh is pasted on the bonding mortar filled in the plate joint and the joint, and the alkali-resistant fiberglass mesh extends 100 mm along both sides of the interface joint.

[0008] Further, it further includes a second structural member and a third structural member. The ALC partition board is arranged between the second structural member and the third structural member. Both ends of the ALC partition board are sleeved with second U-shaped fasteners, and the closed end of the second U-shaped fastener is connected to the second structural member or the third structural member through a fastener.

[0009] Further, there is a gap between the inner end face of the closed end of the second U-shaped fastener and the ALC partition board, and bonding mortar is filled in the gap.

[0010] Further, the width of the gap is less than or equal to 20 mm.

[0011] Further, the fastener is an M12 anchor bolt.

[0012] Further, the second structural member is a structural board or a ring beam.

As a mechanical connector, the U-shaped fastener can resist the wall deformation caused by temperature changes, load effects, etc., thereby improving the stability and durability of the overall structure. Secondly, the adjacent ALC partition boards are spliced through the tight fit of the insertion block and the insertion groove, which not only simplifies the installation process. At the same time, the joint width between the insertion block and the insertion groove is less than or equal to 5 mm, and bonding mortar is filled in the joint, further restricting the relative displacement between the wallboards and enhancing the tightness and stability of the joint.

[0017] (2) A node connection structure between an ALC partition board and a main component provided by the present utility model. In one of the adjacent two ALC partition boards, an embedding groove is provided at the center position of the side end, and in the other of the adjacent two ALC partition boards, an embedding block is fixed at the center position of the side end. When multiple ALC partition boards are spliced, the embedding block is clamped in the embedding groove, and there is a plate joint between the embedding block and the embedding groove. The width of the plate joint is less than or equal to 5 mm, and the plate joint is filled with bonding mortar. With such a design, on the one hand, it ensures that the connection between the ALC partition boards through the embedding block and the embedding groove has sufficient accuracy and tightness, enabling the embedding block to penetrate into the interior of the embedding groove to reach a predetermined embedding depth, thereby enhancing the mechanical biting force at the connection point and improving the connection strength. On the other hand, it enables the bonding mortar to easily penetrate and fill the entire gap to form a continuous sealing layer, effectively preventing the intrusion of harmful substances such as moisture and air, protecting the stability of the internal structure of the wall, not only improving the overall strength of the wall, but also enhancing the seismic resistance, wind resistance and other performances of the wall, enabling the building to maintain its structural integrity when suffering from natural disasters.

Specific embodiments

[0028] The following further describes the embodiments of the present utility model in detail with reference to the drawings and examples. The following detailed description of the examples and the drawings are used to exemplarily illustrate the principle of the present utility model, but cannot be used to limit the scope of the present utility model, that is, the present utility model is not limited to the described embodiments.

[0029] For a better understanding of the present utility model, the present utility model will be further described below in conjunction with the drawings and embodiments:

[0030] See Figures 1 to 5 As shown, a node connection structure between an ALC partition board and a main component provided by the present utility model includes: a plurality of ALC partition boards 1 and a first structural member 2. The plurality of ALC partition boards 1 are arranged side by side. A first U-shaped fastener 3 is provided at the joint of two adjacent ALC partition boards 1. The first U-shaped fastener 3 surrounds the top corners of two adjacent ALC partition boards 1. An embedded groove 11 is provided at the center position of the side end of one of two adjacent ALC partition boards 1, and an embedded block 12 is fixed at the center position of the side end of the other of two adjacent ALC partition boards 1. When the plurality of ALC partition boards 1 are spliced, the embedded block 12 is clamped in the embedded groove 11, and there is a joint between the embedded block 12 and the embedded groove 11. The width of the joint is less than or equal to 5 mm. The width of the joint between the ALC partition board 1 and the first structural member 2 is 10 mm - 20 mm. The bonding mortar 4 is filled at the joint and the joint.

[0031] Specifically, for the node connection structure between the ALC partition board and the main member provided in the embodiment of the present utility model, by arranging the first U-shaped fastener 3 at the joint of two adjacent ALC partition boards 1 and surrounding its top corner, this design effectively enhances the lateral connection strength between the ALC partition boards 1. As a mechanical connecting piece, the U-shaped fastener can resist the wall deformation caused by temperature change, load action, etc., thereby improving the stability and durability of the overall structure. Secondly, the adjacent ALC partition boards 1 are spliced through the close fit between the inserting blocks 12 and the inserting grooves 11, which not only simplifies the installation process. At the same time, the joint design with a joint width less than or equal to 5 mm between the inserting blocks 12 and the inserting grooves 11 is filled with bonding mortar 4 at the joint, further restricting the relative displacement between the wallboards and enhancing the tightness and stability of the joint.

[0032] In this embodiment, a inserting groove 11 is provided at the center position of the side end of one of the two adjacent ALC partition boards 1, and an inserting block 12 is fixed at the center position of the side end of the other of the two adjacent ALC partition boards 1. When multiple ALC partition boards 1 are spliced, the inserting block 12 is clamped in the inserting groove 11, and there is a joint between the inserting block 12 and the inserting groove 11, and the joint width of the joint is less than or equal to 5 mm, and the joint is filled with bonding mortar 4. Such a design, on the one hand, ensures that the connection between the ALC partition boards 1 through the inserting blocks 12 and the inserting grooves 11 has sufficient accuracy and tightness, so that the inserting blocks 12 can penetrate into the interior of the inserting grooves 11 to reach a predetermined embedding depth, thereby enhancing the mechanical biting force of the connection points and improving the connection strength. On the other hand, it enables the bonding mortar 4 to easily penetrate and fill the entire gap to form a continuous sealing layer, effectively preventing the intrusion of harmful substances such as moisture and air, protecting the stability of the internal structure of the wall, not only improving the overall strength of the wall, but also enhancing the earthquake resistance, wind resistance and other performances of the wall, so that the building can maintain the structural integrity when suffering from natural disasters.

[0033] Preferably, the first structural member 2 is a structural wall or a structural column.

[0034] In this embodiment, an alkali-resistant fiberglass mesh 9 is pasted on the bonding mortar 4 filled in the board joints and seams, and the alkali-resistant fiberglass mesh 9 extends 100 mm along both sides of the interface joint. Specifically, as a reinforcing material, the alkali-resistant fiberglass mesh 9 has excellent tensile strength and crack resistance. Pasting it on the bonding mortar 4 can effectively prevent cracks caused by the shrinkage of the bonding mortar 4, temperature changes or external forces. When the wall is subjected to external forces or deformation, the alkali-resistant fiberglass mesh 9 can absorb part of the stress, reduce the generation and expansion of cracks, and thus maintain the integrity of the wall. Secondly, the alkali-resistant fiberglass mesh 9 is closely combined with the bonding mortar 4 to form a stable bonding layer, which not only enhances the bonding force between the bonding mortar 4 and the ALC partition board 1 and the main components, but also improves the overall strength of the entire connection structure. The fiber structure of the alkali-resistant fiberglass mesh 9 can increase the anchoring points of the bonding mortar 4, so that the bonding mortar 4 firmly adheres to the wall.

[0035] See Figures 6 to 7 As shown, it further includes a second structural member 5 and a third structural member 6. The ALC partition board 1 is arranged between the second structural member 5 and the third structural member 6. Both ends of the ALC partition board 1 are sleeved with second U-shaped fasteners 7, and the closed end of the second U-shaped fastener 7 is connected to the second structural member 5 or the third structural member 6 through a fastener 8. In this embodiment, there is a gap between the inner end face of the closed end of the second U-shaped fastener 7 and the ALC partition board 1, and the bonding mortar 4 is filled in the gap. The width of the gap is less than or equal to 20 mm, and the fastener 8 is an M12 anchor bolt.

[0036] In this embodiment, the second structural member 5 is a structural board or a ring beam, the third structural member 6 is a ground beam or a ring beam, and the thickness of the ALC partition board 1 is 200 mm.
